Sometimes SpillStack and Call end up storing onto the stack a value that was just loaded from the same stack location. There was already code in cgSpillStack to avoid the extra stores in some cases, but that still kept the LdStack alive. This diff detects some of those cases with SpillStack in the Simplifier, which allows the LdStack to be eliminated by DCE. This diff also adds similar support for Call. The operands that don't need to be store onto the stack are replaced with None. Note that the optimization in cgSpillStack is not subsumed by this diff. In the Simplifier, we cannot chase through IncRefs as done in cgSpillStack -- that would result in an IncRef that is not consumed.

Installation
You may need to point CMake to the location of your custom libcurl and libevent, or to any other libraries which needed to be installed. The CMAKE_PREFIX_PATH variable is used to hint to the location.
export CMAKE_PREFIX_PATH=/home/user
To build HipHop, use the following:
Linux:
cd /home/user/dev
git clone git://github.com/facebook/hiphop-php.git
cd hiphop-php
git submodule init
git submodule update
export HPHP_HOME=`pwd`
export HPHP_LIB=`pwd`/bin
cmake .
If you are using FreeBSD instead use export - setenv
Once this is done you can generate the build file. This will return you to the shell. Finally, to build, run make. If any errors occur, it may be required to remove the CMakeCache.txt directory in the checkout.
make
